A: Common shareholders of Exelon Corporation as of the close of business on the record date, March 1, 2001, can vote at the annual meeting. Each share of Exelon Corporation common stock gets one vote. - -------------------------------------------------------------------------------- Q.How do I vote? A: Sign and date each proxy card that you receive and return it in the prepaid envelope or vote by telephone or by Internet. If we receive your signed proxy before the annual meeting, we will vote your shares as you direct. You can specify on your proxy whether your shares should be voted for all, some or none of the nominees for director. You can also specify whether you approve, disapprove or abstain from the other proposal. If you do not mark any selections, your proxy card will be voted: . in favor of the election of the directors named in Proposal 1; and . in favor of Proposal 2. You have the right to revoke your proxy at any time before the meeting by: . notifying the Corporate Secretary; or . casting another vote either in person or by one of the other methods discussed above. - -------------------------------------------------------------------------------- Q.Can I vote my shares by telephone or by Internet? A: If you hold your shares in your own name, you may vote by telephone or by the Internet, by following the instructions included on your proxy card. If your shares are held in "street name," you will need to contact your broker or other nominee to find out whether you will be able to vote by telephone or by Internet. - -------------------------------------------------------------------------------- Q:Who will count the vote? A: Representatives of EquiServe Trust Company, N.A., and Exelon Corporation's Office of the Corporate Secretary will count the votes and serve as judges of election. 1

- -------------------------------------------------------------------------------- Q:What constitutes a quorum? A: As of the record date, March 1, 2001, 320,068,089 shares of Exelon Corporation's common stock were issued and outstanding. In order to conduct the annual meeting, more than one-half of the outstanding shares must be present or be represented by proxy. This is referred to as a "quorum." If you submit a properly executed proxy card or vote by telephone or by Internet, you will be considered part of the quorum. Proxies marked as abstaining on any proposal to be acted on by shareholders will be treated as present at the annual meeting for purposes of a quorum. Proxies marked as abstaining, however, will not be counted as votes cast on that proposal. Abstaining proxies include proxies containing broker non-votes. - -------------------------------------------------------------------------------- Q:What vote is needed for these proposals to be adopted? A: More than one-half of shares present either in person or by proxy and entitled to vote at the annual meeting must vote for a proposal in order for it to be adopted. Directors are elected by a plurality, and the six nominees who receive the most votes will be elected. Abstentions and broker non-votes will not be taken into account to determine the outcome of the election of directors or the approval of any proposal. - -------------------------------------------------------------------------------- Q:Who conducts the proxy solicitation and how much will it cost? A: Exelon Corporation is asking for your proxy for the annual meeting and will pay all of the cost of asking for shareholder proxies. We have hired Morrow & Co., Inc. to help us send out the proxy materials and ask for proxies. Morrow & Co.'s fee for these services is $12,000, plus out-of-pocket expenses. We can ask for proxies through the mail or personally by telephone or telegram. We can use directors, officers and regular employees of Exelon Corporation to ask for proxies. These people do not receive additional compensation for these services. We will reimburse brokerage houses and other custodians, nominees and fiduciaries for their reasonable out-of- pocket expenses for forwarding solicitation material to the beneficial owners of Exelon Corporation common stock. - -------------------------------------------------------------------------------- Q:How does a shareholder nominate someone to be a director of Exelon Corporation? A: The deadline for submitting nominations for the 2001 annual meeting passed before the proxy statement was sent to shareholders, and you cannot nominate a candidate from the floor of this year's annual meeting. You may recommend any person as a nominee for director of Exelon Corporation for next year's annual meeting by writing to Mr. M. Walter D'Alessio, Chairman of the Corporate Governance Committee, c/o Exelon Corporation, 10 South Dearborn Street, 37th Floor, P.O. Box 805398, Chicago, IL 60680-5398. Your recommendation must include information required under the Bylaws, including information about the nominating shareholder and the information about the nominee that would be required to be included in a proxy statement under the rules of the Securities and Exchange Commission, as well as the signed consent of the nominee to serve as a director of Exelon if elected. The corporate governance committee has the sole discretion to decide whom it will recommend, and the board has the sole discretion to make the final selection of nominees. You cannot nominate a candidate from the floor of next year's annual meeting unless you have submitted the notice and the information required by the Bylaws to the Corporate Secretary and it is received no later than November 23, 2001. 2

- -------------------------------------------------------------------------------- Q: When are the shareholder proposals for the annual meeting held in the year 2002 due? A: In order to be considered for next year's annual meeting you must submit proposals in writing to Katherine K. Combs, Vice President and Corporate Secretary, Exelon Corporation, 10 South Dearborn Street, 37th Floor, P.O. Box 805398, Chicago, IL 60680-5398. Under the Bylaws, no proposal can be considered at the 2002 annual meeting unless it is received by the Corporate Secretary before the close of business on November 23, 2001. The proposal must also meet the other requirements of the rules of the SEC relating to shareholder proposals. 3

PROPOSALS TO BE VOTED UPON PROPOSAL 1: Election of Directors The board of directors of Exelon Corporation consists of 16 members, divided into three classes. The three-year terms of each class are staggered so that the term of one class expires at each annual meeting. The terms of the six Class I directors will expire at the 2001 annual meeting. The corporate governance committee has recommended, and the board nominates, the following Class I directors for re-election: Carlos H. Cantu, Daniel L. Cooper, G. Fred DiBona, Jr., Sue L. Gin, Edgar D. Jannotta, and Corbin A. McNeill, Jr. Each has consented to serve for a three-year term. If any director is unable to stand for re-election, the board may reduce the number of directors, or designate a substitute. In that case, shares represented by proxies may be voted for a substitute director. We do not expect that any nominee will be unavailable or unable to serve. The corporate governance committee and the board of directors recommend a vote "FOR" these directors. PROPOSAL 2: Ratification of PricewaterhouseCoopers, LLP as Exelon Corporation's Independent Accountants for 2001 PricewaterhouseCoopers and its predecessor firm Coopers & Lybrand have been the independent accountants for PECO Energy Company for many years. The Board of Directors retained PricewaterhouseCoopers to be the independent accountants for Exelon Corporation and its subsidiaries for 2000. The audit committee and the board of directors believe that PricewaterhouseCooper's knowledge of Exelon Corporation and PECO Energy Company is invaluable, especially as Exelon Corporation moves to competition in the energy market. Representatives of PricewaterhouseCoopers working on Exelon Corporation matters are periodically changed, providing Exelon Corporation with new expertise and experience. Representatives of PricewaterhouseCoopers have direct access to members of the audit committee and regularly attend their meetings. Representatives of PricewaterhouseCoopers will attend the annual meeting to answer appropriate questions and make a statement if they desire. In 2000, the audit committee reviewed the PricewaterhouseCoopers Audit Plan for 2001 and proposed fees and concluded that the scope of audit was appropriate and the proposed fees were reasonable. Audit Fees The aggregate fees billed for professional services rendered by PricewaterhouseCoopers LLP for the audit of PECO Energy's and Exelon's annual financial statements for the fiscal year ended December 31, 2000 and for the reviews of the financial statements for the two companies included in the Forms 10-Q they filed were $1,320,837. 4

Financial Information Systems Design and Implementation Fees The aggregate fees for professional services rendered for financial information systems design and implementation by PricewaterhouseCoopers LLP for PECO Energy and Exelon for the fiscal year ended December 31, 2000 were $0. All Other Fees The aggregate fees billed for services rendered by PricewaterhouseCoopers, other that for the services covered in the two preceding paragraphs, for the fiscal year ended December 31, 2000, were $7,930,746. Such services included other accounting and audit services, information technology assurance services, tax services, due diligence, and management consulting services. The audit committee and the board of directors recommend a vote "FOR" PricewaterhouseCoopers, LLP as Exelon Corporation's independent accountants for 2001. 5

This table indicates how much Exelon Corporation common stock was owned by the Company's directors and executive officers as of December 31, 2000. .

Prior to October 20, 2000, the Company's predecessors, Unicom and PECO Energy, had the following committees of their respective boards of directors, which performed functions similar to the functions performed by the committees of the Company's board of directors after October 20, 2000: For Unicom, the Audit and Compliance Committee met four times in 2000, the Business Development Committee met two times in 2000, the Compensation Committee met three times in 2000, and the Governance and Nominating Committee met one time in 2000. For PECO Energy, the Audit Committee met three times in 2000, the Compensation Committee met four times in 2000, the Corporate Governance Committee met two times in 2000, the Finance Committee met eight times in 2000, the Nuclear Committee met ten times in 2000 and the Public Affairs Committee met one time in 2000. Each director attended at least seventy-five percent of the meetings of the board and the meetings of committees of which he or she was a member. BOARD COMPENSATION Employee directors receive no compensation, other than their normal salary, for serving on the board or its committees. Exelon Corporation's total compensation target for directors who are not officers of Exelon Corporation is the median of the general industry average. Directors are paid in cash and deferred stock units as set forth below, and are reimbursed expenses, if any, for attending meetings: $25,000 Annual board retainer $ 1,500 Meeting fee $ 3,000 Annual retainer for chairmanship of committees $50,000 Annual grant of deferred stock units ($ value) Directors are required to own at least 3,000 shares of Exelon Corporation common stock or stock units within three years after their election to the board. Directors can elect to receive all or a portion of their compensation in stock or to defer receiving their compensation until retirement, death or until they no longer serve as director. Deferred compensation is put into an unfunded account and credited with interest, equal to the amount that would have been earned had the compensation been invested in one or more of seventeen mutual funds, including one fund composed exclusively of Exelon common stock.

REPORT OF THE COMPENSATION COMMITTEE What Is Our Compensation Philosophy? Exelon's executive compensation program is designed to motivate and reward senior management for achieving high levels of business performance and outstanding financial results. In 2000, Exelon directed its focus to compensating executives in a manner competitive with high performing energy services companies and general industry firms. This philosophy reflects a commitment to attracting executives from competitive businesses, and retaining key executives to ensure continued focus on achieving long-term growth in shareholder value. The compensation committee, composed of non-employee directors, is responsible for administering executive compensation programs, policies and practices. Exelon's executive compensation program comprises three elements: . Base salary; . Annual incentives; and . Long-term incentives. These components balance short-term and longer-range business objectives and align executive financial rewards with those of Exelon's shareholders. What Factors Do We Consider In Determining Overall Compensation? The committee commissioned a study of compensation programs in the fall of 2000. This analysis was conducted by a leading external management compensation consulting firm and included an assessment of business plans and strategic and competitive compensation levels compared with the external market. While overall, Exelon's total compensation levels were found to be generally competitive, the study results indicated that the mix of compensation components (i.e., salary, annual and long-term incentives and stock options) could be more effectively aligned with the competitive market. Based on those results, Exelon's pay-for-performance philosophy was refined to increase the emphasis on pay-at-risk. Pay will exceed market levels when excellent performance is achieved. Failure to achieve target goals will result in below- market pay. How Do We Determine Base Salary? Base salaries for Exelon's executives are determined based on individual performance with reference to the salaries of executives in similar positions in general industry, and where appropriate, the energy services sector. Base salary is intended to be competitive with comparable markets to attract and retain key executives. Executive salaries are targeted to approximate the median (50th percentile) salaries of the companies identified and surveyed. 14

Mr. McNeill's and Mr. Rowe's 2000 Base Salary: The committee determined Mr. McNeill's and Mr. Rowe's base salaries for serving as the Co-Chief Executive Officers by considering: . a review of competitive data and estimated competitive levels of base pay which were provided by external consulting firms, . performance achieved against financial and operational goals, and . the implementation of Exelon's strategic plans. Mr. McNeill's total annual salary in 2000 was increased from $693,000 to $860,000 on March 1, 2000, and increased to $1,050,000 effective October 20, 2000, the merger closing date. Mr. Rowe's total annual salary in 2000 was increased from $975,000 to $1,050,000 effective October 20, 2000. Other Named Executives' 2000 Base Salary: The base salaries of the other named executive officers listed in the Summary Compensation Table were determined based upon individual performance and by considering comparable compensation data from the industry surveys referred to above. How Are 2000 Annual Incentives Determined? Exelon will establish corporate and business unit measures each year which are based on factors necessary to achieve strategic business objectives. These measures are incorporated into financial, customer and internal indicators designed to assess corporate and business unit performance. The annual incentive awards paid to Exelon executives for 2000 were determined in accordance with the PECO Energy and Unicom incentive programs. Annual incentives were paid to executives based on a combination of the achievement of pre-determined corporate and business unit-specific measures, and individual performance. The incentive plans were designed to tie executive annual incentives to the achievement of key goals of PECO Energy or Unicom, as applicable, and of the executive's particular business unit. For 2000, Mr. McNeill's annual incentive payout was determined using the following corporate performance measures: . Net Income, . Cash Flow, . Average Customer Retention of PECO Energy's Distribution Division, . Customer Value Index of PECO Energy's Distribution Division, . Employee Commitment, . Safety, . Generating Company Capacity Growth, . Exelon Portfolio Growth, and . Merger Integration. 15

For 2000, Mr. Rowe's annual incentive payout was determined using the following corporate performance measures: . Earnings Per Share, . Shareholder Value Added, . Customer Focus Index, . Merger Goals, and . Diversity Goals. 2000 Annual Incentive Award: In evaluating Mr. McNeill's and Mr. Rowe's performance, the Committee considered the overall performance of PECO Energy and Unicom against the measures that were achieved under the applicable incentive program. The committee also considered the leadership demonstrated in positioning Exelon for the future. Mr. McNeill's approved award was $1,081,472 and Mr. Rowe's approved award was $1,180,269. Other Named Executive Officers' 2000 Annual Incentives: The final 2000 incentive award payouts as approved by the committee for the other named executive officers listed in the Summary Compensation Table were determined in accordance with the applicable incentive programs and based on each individual's performance. How Is Compensation Used To Focus Management On Long-Term Value Creation? In 1997, the shareholders of PECO Energy approved an amended long-term incentive plan. The amended plan provides for performance-based awards allowing flexibility in executive compensation practices for a competitive, deregulated business environment. Exelon adopted the PECO Energy long-term incentive plan, and has established a long-term incentive program under the plan that includes a combination of non-qualified stock options (75%) and performance shares (25%). The purpose of stock options is to align compensation directly to increases in shareholder value. Individuals receiving stock options are provided the right to buy a fixed number of shares of Exelon common stock at the closing price of such stock on the grant date. Mr. McNeill and Mr. Rowe each received grants of 266,700 non-qualified stock options on October 20, 2000 and 233,300 non-qualified stock options on January 2, 2001. Other senior executives received grants of two times the target grant size on October 20, 2000 in support of the launch of Exelon and to motivate these executives to achieve aggressive stock appreciation in support of shareholder value. All other executives received a target grant on October 20, 2000. The next scheduled grant of stock options to all executives will occur in 2002. Shortly before the merger became effective, PECO Energy and Unicom terminated and distributed long-term incentive awards to executives under their respective long-term incentive plans (described below). The new Exelon program was launched to focus executives on creating an innovative new company that will be instrumental in changing an entire industry while increasing shareholder value. 16

PECO Energy Long-Term Incentives Restricted Stock Long-term incentives were awarded in the form of restricted stock to retain key executives engaged in positioning PECO Energy. Awards were determined based upon the successful completion of strategic goals designed to achieve long-term business success and increased shareholder value. Depending upon PECO Energy's progress each year, the compensation committee could award restricted stock with prohibitions on sale or transfer until the restrictions lapse. Restricted stock was awarded to key executives after a review of the progress made in repositioning PECO Energy to compete successfully over the long term. The PECO Energy Company Board of Directors approved Mr. McNeill's restricted stock awards of 25,000 shares in 1999 and 32,500 shares in 2000. Stock Options In 2000, Mr. McNeill and other named executives who were executives of PECO Energy received a grant of stock options to align compensation directly to increases in shareholder value. Mr. McNeill's award was for 125,800 stock options. Unicom Long-Term Incentives Performance Units The Unicom long-term performance unit award program was established in 1994 to focus employees on long range performance by linking certain incentive payments to specific performance measures. Incentive opportunities were expressed as a percentage of base salary, and increased with the executive's management level. The awards payable for the period 1999-2000 were based on the total returns of Unicom common stock relative to that of other companies constituting the Dow Jones Utility Index. The awards payable for the period 1999-2001 were based on cumulative shareholder value added and a customer satisfaction index. The awards payable for the period 2000-2002 were based on cumulative earnings per share. Unicom terminated the outstanding long-term incentive awards for the outstanding periods and distributed them as indicated below: . January 1, 1998-December 31, 2000 (full award), . January 1, 1999-December 31, 2001 (two-thirds award), and . January 1, 2000-December 31, 2002 (one-third award). Mr. Rowe's total award under the three programs was $2,143,756. Stock Options In 2000, Mr. Rowe and other named executives of Unicom received grants of stock options to align compensation directly to increases in shareholder value. Mr. Rowe's award was 125,000 Unicom stock options, which were converted to 118,750 Exelon stock options, effective with the merger. 17

Can We Deduct Executive Compensation Under Section 162(m) Of The Internal Revenue Code? Under Section 162(m) of the Internal Revenue Code, executive compensation in excess of $1 million is generally not deductible for purposes of corporate income taxes. However, "qualified performance-based compensation" which is paid pursuant to a plan meeting certain requirements of the Code and applicable regulations remains deductible. The committee intends to continue reliance on performance-based compensation programs, consistent with sound executive compensation policy. Such programs will be designed to fulfill, in the best possible manner, future corporate business objectives. The committee's policy has been to seek to cause executive incentive compensation to qualify as "performance-based" in order to preserve its deductibility for federal income tax purposes to the extent possible without sacrificing flexibility in designing appropriate compensation programs. However, in order to provide executives with appropriate incentives, the committee may also determine, in light of all applicable circumstances, that it would be in the best interests of Exelon for awards to be paid under certain of its incentive compensation programs or otherwise in a manner that would not satisfy the requirements to qualify as performance-based compensation under Code Section 162(m). The portion of incentive compensation that does not qualify as performance-based compensation under Code Section 162(m), and accordingly, to the extent receipt of such compensation is not deferred, the amount of such incentive compensation and salary in excess of $1 million will not be deductible by Exelon for purposes of corporate income taxes. In 2000, Mr. McNeill deferred 50% of his annual and 100% of his long-term incentive awards. Mr. Rowe deferred the portion of his long-term incentive that was payable in 2000 in Unicom common stock under the Unicom Corporation Stock Bonus Deferral Plan. Compensation Committee Edward A.

OPTION GRANTS IN 2000 The "grant date present values" indicated in the option grant table below are an estimate based on the Black-Scholes option pricing model. Although executives risk forfeiting these options in some circumstances, these risks are not factored into the calculated values. The actual value of these options will be determined by the excess of the stock price over the exercise price on the date that the options are exercised. There is no certainty that the actual value realized will be at or near the value estimated by the Black-Scholes option pricing model. The Unicom grants, which expire on January 24, 2010, were adjusted to reflect the substitution of Exelon shares for Unicom shares in accordance with the merger agreement. The original strike price was $37.063. The assumptions used for the Black-Scholes models are as follows: Dividend Risk-Free Expiration Date Volatility Yield Interest Rate Time of Exercise - ------------------------------------------------------------------------------ October 19, 2010 37.23% 3.35% 5.68% 5 years - ------------------------------------------------------------------------------ January 24, 2010 33.64% 4.80% 6.68% 5 years - ------------------------------------------------------------------------------ February 28, 2010 35.18% 4.35% 6.68% 5 years Grant Date Individual Grants Value ------------------------------------------------------------ % of Total Number of Options Securities Granted Grant Date Underlying to Exercise or Present Name and Options Employees Base Price Expiration Value Principal Position Granted (#) in 2000 ($/Sh.)

Mr. McNeill, Mr. Egan, and Mr. McLean were not officers of Unicom Corporation, and were accordingly not eligible for awards under this plan. The awards are based on a three-year performance period. For the awards described in the table, the number of units initially awarded to a participant is determined by dividing a percentage of base salary by $35,432. The applicable percentages for the individuals shown in the table are: 50% for Mr. Rowe; 45% for Mr. Kingsley; 40% for Ms. Strobel; 45% for Mr. Elbert; and 35% for Mr. Helwig. Payouts were to be based on achievement of a cumulative earnings per share goal over the three-year performance period ending December 31, 2002. The dollar value of a payout would be determined by multiplying (a) the number of units applicable by (b) the average closing price of Unicorn common stock as reported in the Wall Street Journal as New York Stock Exchange Composite Transactions during the calendar quarter ending on December 31, 2002 by (c) the level of performance achieved. The three-year period was pro-rated through September 30, 2000 due to the merger, and the amounts paid out are included in the column headed "Long-Term Compensation-- Payouts" in the Summary Compensation Table. 23

RETIREMENT PLANS The following tables show the estimated annual retirement benefits payable on a straight-life annuity basis to participating employees, including officers, in the earnings and year of service classes indicated, under PECO Energy's and Unicom's (by its subsidiary, Commonwealth Edison Company ("ComEd")) non-contributory retirement plans. The amounts shown in the table are not subject to any deduction for Social Security or other offset amounts. Covered compensation includes salary and bonus which is disclosed in the Summary Compensation Table on page 20 for the named executive officers. The calculation of retirement benefits under the plans is based upon average earnings for the highest consecutive five-year period under the PECO Energy Company Service Annuity Plan and for the highest four-year period under the ComEd Service Annuity System. The Internal Revenue Code limits the annual benefits that can be paid from a tax-qualified retirement plan to $170,000 as of January 1, 2001. As permitted by the Employee Retirement Income Security Act of 1974, PECO Energy and ComEd sponsored supplemental plans which allow the payment out of general funds of PECO Energy or ComEd, as applicable, any benefits calculated under provisions of the applicable retirement plan which may be above these limits. Exelon assumed sponsorship of the non-contributory retirement plans and the supplemental plans.

Rowe, 23 years; Oliver D. Kingsley, 23 years; Pamela B. Strobel, 8 years; and David R. Helwig, 8 years; Paul A. Elbert, 19 years. In connection with his resignation, and in accordance with his election, Mr. Elbert received a discounted lump sum payment of $2,677,493 under the supplemental management retirement plan instead of an annuity. 25

EMPLOYMENT AGREEMENTS Employment Agreement with John W. Rowe Exelon entered into an amended employment agreement with Mr. Rowe under which Mr. Rowe will serve as: . co-chief executive officer and president of Exelon, chairman of the executive committee of the Exelon board of directors and a member of the Exelon board of directors during the first half of the transition period provided for in Exelon's Bylaws, which is defined as the period from the effective time of the merger forming Exelon (October 20, 2000) until December 31, 2003, . co-chief executive officer of Exelon, chairman of the Exelon board of directors and a member of the Exelon board of directors during the second half of the transition period, and . chief executive officer of Exelon, chairman of the Exelon board of directors and a member of the Exelon board of directors after the transition period. Mr. Rowe will succeed to the position of sole chief executive officer of Exelon or chairman of the Exelon board of directors if: . prior to the end of the transition period, Mr. McNeill should cease to be a co-chief executive officer of Exelon or the chairman of the Exelon board of directors, and . Mr. Rowe is still a co-chief executive officer of Exelon at that time. Mr. Rowe will receive an annual base salary of: . at least $900,000 through March 15, 2001, but not less than his base salary immediately prior to the completion of the merger ($975,000), or . Mr. McNeill's base salary, whichever is higher. After March 15, 2001, Mr. Rowe's base salary will be determined by Exelon's compensation committee. Mr. Rowe will be eligible to participate in annual incentive award programs, long-term incentive plans and stock option plans on the same basis as other senior executives of Exelon. The agreement provided that a grant of options would be considered at the time the merger was completed. Mr. Rowe is entitled to participate in all savings, deferred compensation, retirement and other employee benefit plans generally available to other senior executives of Exelon. During the transition period, Mr. Rowe's base salary and participation in the plans and awards described in this paragraph will be on a basis that is not less than that of Mr. McNeill's or on which Mr. McNeill participates. Under his amended employment agreement, Mr. Rowe will receive a special supplemental executive retirement plan, or SERP, benefit if: . he terminates due to normal retirement, early retirement, termination without cause, termination for good reason, death or disability, or . he voluntarily terminates on or after the first anniversary of the completion of the merger for any other reason. The term "good reason" includes the failure to appoint Mr. Rowe to the management and Exelon board of director positions described above. The special SERP benefit will equal the SERP benefit that Mr. Rowe would have received: . if he had attained age 60 (or his actual age, if greater), and 26

. if he had earned 20 years of service on March 16, 1998 and one additional year of service on each anniversary after that date and prior to termination. Except as provided in the next paragraph, if Exelon terminates Mr. Rowe's employment for reasons other than cause, death or disability or if he should terminate employment for good reason on or after December 31, 2004 and not within 24 months following a change in control of Exelon, he would be entitled to the following benefits: . a prorated annual incentive award for the year in which termination occurs, . severance payments equal to his base salary for two years after termination, and for each year during such period an amount equal to the average of the annual incentive awards paid to him with respect to the three years preceding the year of termination or, if greater, his annual incentive award for the year before termination, . for the two-year period, continuation of his life, disability, accident, health and other welfare benefits, plus the retirement benefits described above and post-retirement health care coverage, . all of his exercisable options would remain exercisable until the applicable option expiration date, . unvested options would continue to become exercisable during the two- year continuation period and thereafter remain exercisable until the applicable option expiration date, and . all compensation earned through the date of termination and coverage and benefits under all benefit plans to which he is entitled. Mr. Rowe will receive the termination benefits described in "Change in Control and Severance Arrangements" below, rather than the benefits described in the previous paragraph, if Exelon terminates Mr. Rowe without cause or he terminates with good reason and . the termination occurs within 24 months after a change in control of Exelon, or . the termination occurs at any other time prior to the earlier of normal retirement or December 31, 2004, or . the termination occurs at any other time on or after the completion of the merger and before normal retirement because of the failure to appoint or elect Mr. Rowe to the management or Exelon board of director positions described above. Employment Arrangement with Corbin A. McNeill, Jr. Although Exelon has not entered into an employment agreement with Mr. McNeill, the merger agreement provided that at any time during the transition period when Messrs. McNeill and Rowe are co-chief executive officers, each of them will receive the same salary, bonus and other compensation (including option grants and other incentive awards and all other forms of compensation) and enjoy the same other benefits and the same employment security arrangements as the other. Employment Agreement with Oliver D. Kingsley, Jr. ComEd entered into an employment agreement with Oliver D. Kingsley, Jr. pursuant to which he became Executive Vice President and President and Chief Nuclear Officer--Nuclear Generation Group, effective November 1, 1997. The agreement provides for a guaranteed increase in annual base salary of at least 4% per year, beginning in 1999. 27

Mr. Kingsley received an option to purchase 25,000 shares of common stock with an option price equal to the fair market value of the common stock as of November 1, 1997. Such options became exercisable in equal installments on November 1 of 1998, 1999 and 2000, and expire on October 31, 2007. Mr. Kingsley also received a grant of 20,000 shares of restricted stock that vested in equal installments on November 1 of 1998, 1999 and 2000. The employment agreement with Mr. Kingsley provides that Mr. Kingsley will participate in Unicom's Annual Incentive Award Program and will receive an annual incentive award for 1998 and 1999 at least equal to the target award of $213,750. Mr. Kingsley participates in the Unicom Long-Term Performance Unit Award Program, and any award payable under such Program with respect to the three- year performance periods ending on December 31, 1997, 1998, or 1999 will be made as though he had participated in the Program throughout such performance periods (except in the case of a termination of employment). In addition, Mr. Kingsley received $375,000 as an inducement to enter into the employment agreement, and an annual living cost allowance equal to $75,000 (increased by the amount of applicable taxes on such amount as so increased) for the first three years of the agreement term. Mr. Kingsley's employment agreement provides for a retirement benefit equal to the amount that would have been payable under the Service Annuity System (plus amounts payable under the ComEd Supplemental Management Retirement Plan) for an employee who retires at age 60 calculated based on the assumption that Mr. Kingsley had completed 15 years of credited service beginning with the third year of his employment and that such credited service increased by five years during each of the next two years, in addition to his actual years of credited service after five years of employment. The employment agreement with Mr. Kingsley provides for a lump sum severance payment to Mr. Kingsley if he should be terminated without cause equal to two times his base salary at the time of such termination, and a continuation of health and life insurance benefits for two years after the date of termination, plus retirement benefits (calculated as though he had completed at least 15 years of credited service if such termination occurs during the first two years of employment) and retire health care coverage. In addition, any unvested portion of the restricted stock granted under the agreement will immediately become fully vested and nonforfeitable. These benefits have been incorporated into a change in control severance agreement that became effective on October 20, 2000. See "Change in Control Severance Agreements" below. Mr. Kingsley agreed not to use for his own benefit or disclose any confidential information of Unicom or ComEd during or after the term of his employment, and not to solicit any employee of ComEd for one year after the term of his employment with ComEd. Severance Agreement with Paul Elbert Paul Elbert's resignation from all offices on December 1, 2000 was a qualifying termination under his change in control severance agreement. Pursuant to the agreement, he received a severance payment equal to $2,208,750 (three times the sum of his annual base salary and target incentive award at the time of his termination). He also received a retirement benefit under the Supplemental Management Retirement Plan (SERP) equal to the retirement benefit that would have been payable under the Service Annuity System (and the SERP) to employees who retire at age 60 28

calculated as though he had completed 18 years of credited service as well as his actual years of credited service. In addition, medical and other welfare benefits continue to be provided for three years, after which Mr. Elbert is entitled to elect post retirement coverage for himself and his eligible dependents. Mr. Elbert received payment of an amount equal to his target annual incentive for 2000. Unvested options become exercisable as of his termination date and the restrictions on his awards of restricted stock lapsed as of that date. Pursuant to the agreement, Mr. Elbert also received a payment of $2,154,968 to cover the excise taxes imposed under Section 4999 of the Internal Revenue Code. Change in Control Severance Arrangements PECO Energy and Unicom entered into change in control agreements with certain senior executives which became effective upon the completion of the merger. The agreements cover employment through October 20, 2002 and generally protect executives' positions and compensation levels through that date. A material adverse change in such compensation or position is included in the definition of "good reason" for purposes of the agreements. If an executives resigns for good reason before October 20, 2001 or if the executive's employment is terminated by the company other than for cause, severance pay and benefits become payable. The severance payments and benefits provided under the agreements include: . Severance payments equal to three multiplied by the sum of: . the employee's annual base salary, plus . an amount equal to the average of the annual incentive awards paid to the employee for the two years preceding the year of termination or, if greater, the target award under the annual incentive award program in which the employee participates for the year in which termination occurs. . A prorated annual incentive award for the year in which termination occurs. . Continuation of life, disability, accident, health and other welfare benefit coverage for three years and thereafter, if applicable, retiree coverage is available. . Outplacement services. . All of a terminated employee's exercisable options remain exercisable until the applicable option expiration date, and all unvested options become fully exercisable and remain so until the applicable option expiration date. . Any deferred stock units, restricted stock, or restricted share units become fully vested and any other long-term incentive plan award which is unvested would vest. . For purposes of determining benefits under the supplemental retirement plan or arrangement, in which the employee participates, the employee will be credited with three additional years of credited service, age and compensation. . For purposes of determining eligibility for retiree welfare benefits, the employee will be deemed to have three additional years of service and age. . All compensation earned through the date of termination as well as all coverage and benefits under all benefit plans to which the employee is entitled. Pursuant to the terms of offers of employment or employment agreements, certain employees are also entitled to additional service credits for purposes of retiree health care eligibility and for determining benefits under the supplemental retirement plan or arrangement in which they participate. 29

In connection with the severance benefits described above, each executive who was an employee of PECO Energy prior to the merger is subject to a non- compete agreement for 24 months from the applicable termination date. Although a participating employee does not have a duty to mitigate the amounts due from the company, continued welfare benefit coverage would be offset during the applicable continuation period by comparable coverage provided under welfare plans of another employer. Employees who are senior vice-presidents will receive an additional payment to cover excise taxes imposed under Section 4999 of the Internal Revenue Code on "excess parachute payments" or under similar state or local law if the after-tax amount of payments and benefits subject to these taxes exceeds 110% of the "safe harbor" amount that would not subject the employee to these excise taxes. If the after-tax amount, however, is less than 110% of the safe harbor amount, payments and benefits subject to these taxes would be reduced or eliminated to equal the safe harbor amount. Benefits payable to other employees subject to the excise taxes imposed under Section 4999 of the Internal Revenue Code will be reduced to the employees's safe harbor amount. 30

REPORT OF THE AUDIT COMMITTEE The Audit Committee reviews Exelon Corporation's financial reporting process on behalf of the Board of Directors. In fulfilling its responsibilities, the committee has reviewed and discussed the audited financial statements contained in the 2000 Annual Report on SEC Form 10-K with Exelon Corporation's management and the independent auditors. Management is responsible for the financial statements and the reporting process, including the system of internal controls. The independent auditors are responsible for expressing an opinion on the conformity of those audited financial statements with accounting principles generally accepted in the United States. The committee discussed with the independent auditors the matters required to be discussed by Statement on Auditing Standards No. 61, Communication with Audit Committees, as amended. In addition, the committee has discussed with the independent auditors the auditors' independence from Exelon Corporation and its management, including the matters in the written disclosures required by Independence Standard Board Standard No. 1, Independence Discussions with Audit Committees. In reliance on the reviews and discussions referred to above, the committee recommended to the Board of Directors (and the Board has approved) that the audited financial statements be included in Exelon Corporation's Annual Report on SEC Form 10-K for the year ended December 31, 2000, for filing with the Securities and Exchange Commission Audit Committee Carlos H. Cantu, Chair Sue L. Gin Richard H. Glanton John M. Palms 31

OTHER INFORMATION Transactions with Management: Pamela B. Strobel, is an Executive Vice President of Exelon Corporation, the President of Exelon Energy Delivery Company, and the Vice Chair of Commonwealth Edison Company (ComEd), both of which are subsidiaries of Exelon Corporation. Ms. Strobel's husband, Russ M. Strobel, was elected Senior Vice President, General Counsel and Secretary of Nicor Inc. ("Nicor") in January 2001. Since January 1, 2000, Nicor Gas and ComEd have been parties to the following transactions, proposed transactions or business dealings: (1) Nicor Gas and ComEd are parties to an interim agreement approved by the Illinois Commerce Commission under which they cooperate in cleaning up residue at former manufactured gas plant sites. Under the interim agreement, costs are split between Nicor Gas and ComEd, except that if they cannot agree upon a final allocation of costs, the interim agreement provides for arbitration. For the year 2000, Nicor Gas billed ComEd approximately $3,000,000 under the interim agreement, and ComEd billed Nicor Gas approximately $3,950,000. For year 2001, Nicor Gas estimates that it will bill ComEd $4,450,000 and that ComEd will bill Nicor Gas $12,575,000; (2) Nicor Gas has made a proposal to utilize approximately 23 miles of ComEd's right of way starting in 2001 in connection with a pipeline project. No agreement has been reached and no consideration has been agreed to; (3) Nicor Gas and ComEd are parties to a three-year agreement entered into in May 2000 pursuant to which Nicor Gas transports gas to an electric generating station in Rockford, Illinois.

Section 16(a) Beneficial Ownership Reporting Compliance: Based solely upon a review of copies of Section 16 reports provided to Exelon Corporation and written representatives received from directors and executive officers that no other reports were required during 2000, Exelon believes that its directors and executive officers made all required filings during 2000 with one exception. Mr. Brennan acquired shares of Exelon as the result of the conversion of Unicom Corporation shares that he acquired prior to Unicom's merger with Exelon. The Unicom shares were acquired for Mr. Brennan by a broker having the discretionary authority to do so under a standing brokerage account. Mr. Brennan was not aware of the share acquisition, and did not file a timely report. Mr. Brennan became aware of the acquisition after the shares were sold in January 2001, and that sale was timely reported. Discretionary Voting Authority: A shareholder submitted a proposal to adopt a policy on investing in clean energy. The shareholder was ineligible to have the proposal included in the proxy statement and it was excluded under the rules of the Securities and Exchange Commission. In the event this proposal were to properly come before the 2001 Annual Meeting, it is the intention of the individuals serving as proxies to vote against the proposal. The board of Exelon Corporation knows of no other matters to be presented for action at the meeting. As to any other matters that may properly come before the meeting, the individuals serving as proxies intend to vote in their best judgment. Your signed proxy card gives authority to Randall E. Mehrberg and Katherine K. Combs to vote on these matters. 32

APPENDIX AUDIT COMMITTEE CHARTER ORGANIZATION Membership The Committee shall consist of at least three directors, all of whom are "independent", which means that they have no relationship to the Company that may interfere with the exercise of their independence from management and the Company. Membership is determined by the Board on the recommendation of the Corporate Governance Committee. During the Merger Transition Period, the committee will be comprised of an equal number of members of the former PECO and Unicom Boards. Each member of the Committee shall be "financially literate", or shall become financially literate within a reasonable period of time after his or her appointment to the Committee. The Board has defined "financial literacy" to mean familiarity with the Company's financial statements, including its balance sheet, income statement and cash flow statement, and general knowledge of key business and financial risks and related controls or control processes. Such knowledge may be acquired after appointment to the committee through company-sponsored education or review of educational materials or other resources. At least one member of the Committee shall have "accounting or related financial management expertise". The Board has defined accounting or related financial management expertise to mean a solid background in finance, accounting or auditing, acquired through past employment experience, professional certification, or any other comparable experience that results in the individual's financial sophistication, including being or having been a chief executive officer or other senior officer with significant financial oversight responsibilities. In addition to the definition of "independent" above, the following restrictions shall apply to every Committee member: 1. Employees. A director who is an employee (including non-employee executive officers) of the Company or any of its affiliates may not serve on the Committee until three years following the termination of his or her employment. In the event the employment relationship is with a former parent or predecessor of the Company, the director could serve on the Committee after three years following the termination of the relationship between the Company and the former parent or predecessor. 2. Immediate Family. A director who is an immediate family member (including parents, spouse, children, in-laws, siblings and anyone who shares such a person's home) of an executive officer of the Company or any of its affiliates can not serve on the Committee until three years following the termination of the officer's employment. 3. Business Relationship. A director who is a partner, controlling shareholder, or executive officer of an organization that has a business relationship with the Company (e.g., supplier or customer), or who has a direct business relationship with the Company (e.g., attorney, consultant, advisor) may serve on the Committee only if the Board determines in its business judgment, considering the materiality of the relationship, that the relationship does not interfere with the director's exercise of independent judgment. The Board has the sole discretion to determine whether any such relationship is "significant" on a case by case basis, depending on the volume of business, its importance to the director, his or her business or the Company, and the degree to which the 33

relationship could affect the judgment of a person in the director's position. Three years after the termination of the business or partnership relationship, the director may serve on the Committee without any requirement that the Board make such a determination. 4. Cross Compensation Committee Link. A director who is employed as an executive of another corporation where any of the Company's executives serves on that corporation's compensation committee may not serve on the Audit Committee. 5. Independence Override. One director who is no longer an employee, or who is an immediate family member of a former executive officer, but who would not be considered independent due to the three year restriction period, may be appointed, under exceptional and limited circumstances, to the Committee if the Board determines in its business judgment that membership is required by the best interests of the Company and its shareholders, and the Company discloses in the next annual proxy statement the nature of the relationship and the reason for that determination. Meetings The Committee meets quarterly, or more frequently as circumstances require. Regular meetings are scheduled in accordance with the annual schedule approved by the Board. A majority of the members of the Committee shall constitute a quorum for the transaction of business. Minutes are recorded by the Secretary to the Committee. Approval by a majority of the members present at a meeting at which a quorum is present shall constitute approval by the Committee. The Committee may also act by unanimous written consent without a meeting. The Chairman, the Co-CEOs, the other Senior Officers of the Company, the Internal Auditor and representatives of the Company's outside auditors attend meetings at the invitation of the Committee. BASIC FUNCTION AND PURPOSE The Audit Committee assists the Board of Directors in fulfilling its responsibility to oversee and review the Company's financial reporting and accounting practices, audit functions and internal controls. The Committee also reviews and makes recommendations to the Board on risk management policy and risk limits. In addition, the Committee oversees and reviews officers' and directors' expenses, compliance with appropriate policies, and the Code of Business Conduct, and environmental, legal and regulatory compliance. RESPONSIBILITIES Outside Auditors The Committee shall: 1. Recommend to the Board of Directors the selection and retention of an outside auditor to perform the annual audit of financial statements and the appropriate fees to compensate the outside auditor. The outside auditor is ultimately accountable to the Board and the Committee. The Board and the Committee have the ultimate authority to select, evaluate, and, where appropriate, replace the outside auditor, subject to ratification by the shareholders. 34

2. Consider, in consultation with the outside auditor and management, the planned scope of the annual audit of financial statements, including a review of staffing and coordination of audit efforts between the outside auditor and the internal auditor. 3. Review and satisfy itself of the independence of the outside auditor, including a review of any out-of-scope services, and related compensation provided to the outside auditor. To that end, the Committee shall request that the outside auditor submit to the Committee on a periodic basis a formal written statement delineating all relationships between the auditor and the Company consistent with Independence Standards Board Standard No. 1. The Committee is responsible for actively engaging in a dialogue with the outside auditor with respect to any disclosed relationships or services that may effect the objectivity and independence of the outside auditor, and for recommending that the Board take appropriate action to satisfy itself of the outside auditor's independence. 4. Consider and review with the outside auditor and management: a) the adequacy of the Company's internal controls; b) the Company's annual financial statements and related footnotes; c) emerging accounting standards and issues affecting the Company; d) any significant and related findings and recommendations of the outside auditor, together with management's response. The Committee shall discuss with the outside auditor the auditor's judgments about the quality, not just the adequacy, of the Company's accounting principles as applied in its financial statements. This discussion, usually with management present, will include such matters as consistency, clarity and completeness of the disclosures, as well as items having a significant impact on the representational faithfulness, verifiability, neutrality and consistency of the accounting information. 5. Direct the outside auditor to conduct an SAS 71 interim review of quarterly financial statements prior to filing of the quarterly report on Form 10-Q with the Securities and Exchange Commission. The outside auditor and/or financial management will attempt to discuss with the Committee, or at least the Committee chair, the results of the SAS 71 review if the SAS 71 review reveals significant adjustments, management adjustments and accounting estimates, significant new accounting policies or disagreements with management. The discussion should be attempted prior to the quarterly report on Form 10-Q, or as soon as practicable afterwards. 6. At least annually, at a regularly scheduled meeting of the Committee, meet privately with the outside auditor without members of management in attendance. Internal Auditing The Committee shall: 1. Consider and review with management the annual work plan and planned activities of the internal auditor, the budget and staffing for the internal audit function, the Charter of the internal auditor, and the degree of compliance of the internal audit function with the Standards for the Professional Practice of Internal Auditing (IIA). 2. Consider and review the coordination of audit efforts between the internal audit staff and the outside auditor to ensure completeness of coverage and efficient use of audit resources. 35

3. Consider and review with management and the internal auditor significant internal auditing findings and recommendations related to the adequacy of internal controls, compliance with policies and procedures, and effective and efficient use of Company resources; also consider and review management's response to the audit recommendations. 4. Meet privately with the internal auditor, as the Committee deems appropriate. At least annually, meet in executive session with the internal auditor at a regularly scheduled meeting of the Committee. Risk Management Policy and Risk Limits The Committee shall review and make recommendations to the Board on risk management policy and risk limits. Officers' and Directors' Expenses, Code of Business Conduct and Environmental, Legal and Regulatory Compliance The Committee shall: 1. Review policies and procedures with respect to officers' and directors' expense accounts and perquisites, including their use of corporate assets; and consider the results of and reviews of officers and directors expenses and perquisites by the internal auditor or the outside auditor. 2. Review policies and procedures with respect to prevention of illegal payments, conflicts of interest, or other questionable practices; and consider the results of monitoring of compliance with the Code of Business Conduct, particularly by officers and directors. 3. Review policies and procedures with respect to environmental compliance programs and recognition of contingent liabilities resulting from identified environmental problems; and consider the results of any environmental compliance assessments performed by Environmental Affairs, Internal Auditing, or the outside auditor. 4. Review significant legal matters, including the Company's compliance with applicable laws and regulations. Review the Company's use of outside counsel to provide legal services and the fees for those services. ANNUAL ASSESSMENT OF PERFORMANCE AND CHARTER REVIEW The charter shall be approved by the Board of Directors. The Committee shall annually assess its own performance and review the adequacy of its charter. The text of the charter will be included in the proxy statement at least once every three years. REPORTING RESPONSIBILITY 1. All action taken by the Audit Committee shall be reported to the Board of Directors at its next meeting succeeding such action. 2. The Committee shall make annual reports to the NYSE stating: (a) whether the Board made any determination regarding the independence of directors; (b) whether all members of the 36

Committee are financially literate; (c) whether at least one member of the Committee has accounting or related financial management expertise; and (d) whether the Committee reviewed and assessed the adequacy of the Committee charter. 3. The Committee shall include in the annual proxy statement a report disclosing whether the Committee has a charter that has been approved by the Board; the text of the charter will be included in the proxy statement every three years. The Committee will annually disclose whether the discussions with management, the inside and outside auditors took place, and whether, based on its review of the financial statements, the Committee recommended to the Board that it include the financial statements in the annual report on Form 10-K. 37
